Solution Overview
Problem
Existing communication systems face limitations in supporting extended communication distances and reliability, particularly in scenarios involving device-to-device and vehicle-to-everything communications, where traditional relay mechanisms do not adequately address coverage and reliability issues.
Innovation Solution
The implementation of multi-hop relay links based on trigger conditions related to link status, allowing terminals to select or reselect relay terminals dynamically, enhancing communication reliability and coverage through a network of interconnected relays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional relay mechanisms are used, then communication can be extended beyond direct range, but communication reliability and coverage remain insufficient
Solution Approach 1:
The patent segments the relay communication process into multiple independent hops, where each terminal can independently select and switch between relay terminals. This segmentation allows the system to extend coverage through multiple relays while maintaining reliability by enabling independent failure isolation and switching at each hop.
Solution Approach 2:
The patent implements dynamic relay selection and reselection mechanisms triggered by link status changes. Terminals can dynamically switch between direct and relayed communication modes, or between different relay terminals, based on real-time link conditions. This dynamics resolves the contradiction by adapting the communication path to maintain reliability while extending coverage.
2Length of moving object
If multi-hop relay links are implemented, then communication distance is extended, but system complexity increases
Solution Approach 1:
The patent enables terminals to autonomously perform relay selection, link status monitoring, and mode switching without centralized control. Each terminal independently evaluates link conditions and selects appropriate relay terminals based on pre-configured trigger conditions. This self-service approach extends communication distance through multi-hop relaying while minimizing system complexity by distributing intelligence to individual terminals.
Solution Approach 2:
The patent changes the operational parameters of terminals by introducing trigger condition-based relay selection. Instead of continuous complex decision-making, terminals monitor specific link status parameters and switch modes or select relays when predefined thresholds are met. This parameter-based approach simplifies the control logic while enabling extended communication distances through coordinated multi-hop relaying.

AI summary
The present application relates to a relay communication method and a device. The method comprises: on the basis of a first trigger condition, a first terminal selects a relay terminal meeting a requirement of the first terminal, wherein the first terminal and the relay terminal are in a multi-hop relay link, and the first trigger condition is related to a link status. In embodiments of the present application, selection of a relay can be triggered on the basis of a trigger condition to form a multi-hop relay link, thereby improving the communication reliability and expanding the communication range.
